'Multi-core'. You can shift multiple processes around on multiple CPUs.

And then there's the nastiness of thread-blocking. In such a case, a
process possibly has to wait for a thread to complete. That is not
really desirable, if you have more than one concurrent request.

Also, if one process gets into a deadlock, it doesn't take your whole
web-server with it.
